The CPX 928 is a single slot PLC CPU that is
programmed and configured by MS-DOS or
Windows based programming software to perform
real time control of machines, processes and material
handling systems. It communicates with I/O and
smart option modules over the rack-mounted
backplane using the VME C.1 Standard format.
Supported option modules include LAN Interface
modules, Programmable Coprocessor, Alphanumeric
Display Coprocessor, Bus Controller for IC660/661 I/O
products, Communications modules, I/O Link
Interface, and all of the IC697 family of discrete and
analog I/O modules.User RAM Memory
The CPX928 has a built-in memory board with 6
Mbytes of battery-backed CMOS RAM memory for
user data (program, configuration, and register data)
storage.
User Flash Memory
The CPX928 has 256K of built-in, non-volatile flash
memory for user data (program, configuraton, and
register data) storage. Use of this flash memory is
optional.
Firmware Storage in Flash Memory
This CPU uses flash memory for storing the operating
system firmware. This allows firmware to be updated without disassembling the module or replacing
EPROMs. The operating system firmware is updated
by connecting a PC compatible computer to the module’s serial port and running the software included
with the firmware upgrade kit.
Operation, Protection, and Module Status
Operation of this module can be controlled by the
three-position RUN/STOP switch or remotely by an
attached programmer and programming software.
Program and configuration data can be locked
through software passwords or manually by the
memory protect keyswitch. When the key is in the
protected position, program and configuration data can
only be changed by a programmer connected parallel
only (to the Bus Transmitter module). The status of a
CPU is indicated by the seven green LEDs on the
front of the module.
